§ 1.381(c)(21)-1. Pre-1954 adjustments resulting from change in method of accounting.

¶(a) Carryover requirement. Section 381(c)(21) provides that, in a transaction to which section 381(a) applies, an acquiring corporation shall take into account the net amount of any adjustments described in section 481(b)(4) (relating to adjustments arising from changes in accounting methods initiated by the taxpayer attributable to pre-1954 Code years) of the distributor or transferor corporation to the extent that such net amount of such adjustments has not been taken into account in any taxable year, including a short taxable year, by the distributor or transferor corporation. The acquiring corporation shall take into account in each taxable year beginning with the taxable year ending after the date of distribution or transfer the net amount of such adjustments in the same manner and at the same time as such net amount would have been taken into account by the distributor or transferor corporation. Thus, the amount of any such adjustment which the acquiring corporation shall take into account in each taxable year shall be the same amount that would have been taken into account in each taxable year by the distributor or transferor corporation.

¶(b) This section may be illustrated by the following example:

¶(c) Successive transactions to which section 381(a) applies. The provisions of this section shall apply in the case of successive transactions to which section 381(a) applies. Thus, if R Corporation, which was taking into account adjustments described in section 481(b)(4), distributes or transfers its assets to S Corporation in a transaction to which section 381(a) applies, and S Corporation was required to take into account any remaining portion of such adjustments under section 381(c)(21) and this section, and if subsequently S Corporation distributes or transfers its assets to T Corporation in a transaction to which section 381(a) applies, then T Corporation, under section 381(c)(21) and this section, shall take into account any remaining portion of such adjustments not previously taken into account by R and S Corporations.

¶(d) Acquiring corporation not receiving all the assets. The adjustments described in this section acquired from a distributor or transferor corporation by an acquiring corporation in a transaction to which section 381(a) applies is not reduced by reason of the fact that the acquiring corporation does not acquire 100 percent of the assets of the distributor or transferor corporation.
